Installing this fixed the problem but in return, i've lost all my contacts. My gut feeling just tells me that my contacts is still somewhere in my phone since i did not do anything else other den installing this fix.

Anyone has any idea how do i reverse this fix? I've tried installing to no avail, and after uninstalling, i can't install it again, so i believe i may have to do some manual work to reverse this fix.

Help please. My business contacts are all in my phone with no backup at all.
